Total and total ionization cross sections for NH$_{x}$ and NF$_{x}$ (x = 1,2 and 3) on electron impact

POSTER

Abstract

Electron-impact induced ionization cross-sections for NH$_{3}$ and NF$_{3}$ and their chemically reactive free radicals, NH$_{X}$ {\&} NF$_{X}$ (x = 1,2) are relevant to processes in planetary {\&} cometary atmospheres. In this paper we have reported the total (complete) and total ionization cross sections for molecules NH$_{X}$ and NF$_{X}$ (x = 1,2 and 3) on electron impact from threshold to 5 keV. We used complex optical potential formalism (SCOP) [1] to calculate the total inelastic cross sections Q$_{inel}$ and total (complete) cross sections Q$_{T}$ Q$_{inel}$ includes Q$_{ion}$ and we have developed a semi-empirical method, Complex Scattering Potential -- ionization contribution (CSP-ic) to extract ionization cross sections Q$_{ion}$ from calculated Q$_{inel}$ [2]. \textbf{References} [1] M.Vinodkumar, K.N.Joshipura, C.G.Limbachiya {\&} B.K.Antony, Eur.
